4% slip, that is amazing for a pleasure boat

gps,tell tale tach and 10key dont lie! that thing was locked up tight at high speed. if i remember it was 6700rpm-118mph-1:50 gears 30p5x im close i know. damn rocket ship 97 25' eliminator high "x" mounted gimbal and 2" shorty. took a while to get on plane pulled hard thru mid range and shot from 90mph up... damn i miss that boat

with the numbers you have i get 7%, still good,what was prop shaft to bottom? i am working on a buddys 26 daytona an am unfamiliar with eliminator set ups.

almost 2" above the bottom of the outer keel lines. mine had a delta pad 2 step bottom so off the center pad it was about 3 1/2" below that.hope this helps
